Here's a thought, instead of approaching a business and flat out asking them for money, get them involved first. Expand your team to their children (if they have any) so then they feel obligated to help out (Networking as mentioned above). Work with them, maybe start a committee who you report to what you have done and ask for any and all suggestions. I'm guessing that if a company is involved in the organization, they will have a lot more want and need to help it. Finally, make sure you award them back at the end of the year just to say "Thanks" for helping you out.
